Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475070, here are decompositions:

17 + 31475053 = 31475070
41 + 31475029 = 31475070
61 + 31475009 = 31475070
71 + 31474999 = 31475070
73 + 31474997 = 31475070
89 + 31474981 = 31475070
101 + 31474969 = 31475070
139 + 31474931 = 31475070

Showing the first eight; more decompositions exist.
